Ultimate origin

Pronunciation

  • IPA (Classical): [seːˈroː.tɪ.nʊs][1]
  • IPA (Ecclesiastical): [seˈrɔː.ti.nus][1]

Forms

sērōtinus (feminine sērōtina, neuter sērōtinum); first/second-declension adjective[1]

Etymology

It is from the adverb sērō “late” with -tinus, from sērus “late”.[2][1][3] De Vaan traces ⟨sērus⟩ to Proto-Italic *sēro- (“(too) late”), Proto-Indo-European *seh₁-ro- (“long-lasting; late”), cognate with Old Irish sír (“lasting”) and Welsh hir (“long”).[4]

Earliest recorded meaning

Köbler's earliest source is Seneca.[5] Köbler dates Seneca 4 BC–65 AD.[5]

Semantic evolution

It meant coming or happening late, belated, deferred, and of plants late-flowering, late-ripening, and Lewis & Short note it as an agricultural term of the Augustan period for the classical ⟨sērus⟩.[2][6]

In Ecclesiastical Latin it means late.[7] Medieval Latin used it for “of the evening”, and the neuter for evening.[8] It survives as Spanish serondo and Portuguese serôdio, and English serotine (1590s) is from it through French.[1][3]
